Static adapter build yields 404 error when setting 'config.kit.paths.base'

[jawshoeadan]

Describe the bug

I have a simple SvelteKit project that is hosted on GitHub Pages, so I have to set the base path to the repository name. I did so in svelte.config.js. Then, I built the project with npm run build. The project yields this error (full log below): > 404 /_app/start-6109155a.js (linked from /)

Reproduction

This is the repository that I'm building my project in. As you can see, I have a GitHub Actions workflow that deploys the website to GitHub Pages statically. Because of the error that is yielded, I just bypass it using || true after the build command. The website fully works after deployed so I'm wondering if there is something I'm doing wrong in my repo or if the error is not supposed to be thrown.

To reproduce:

1. $ git clone https:/jawshoeadan/simple-svelte-covid-tracker.git
2. $ npm install
3. $ npm run build

Thank you in advance to anyone who can help.
